Practical aspects of operating surface runoff treatment facilities
in winter period

Summary

The core indicators of the operation of surface runoff treatment facilities in winter period are cited. The results of snow melt composition study obtained from the samples of fresh snow and samples taken from road surfaces in Moscow and different industrial areas are presented. The analysis was carried out at the MosvodokanalNIIproject laboratory for municipal, industrial-rain water and sludge treatment. Based on the chemical and analytical studies the multicomponent chemical composition of snow mass was determined that reflected the large-scale impact of anthropogenic and natural factors. The kinetics of the suspended substances in snow melt sedimentation in a snow melter section of the retention tank of the treatment facilities is shown. The process of snow mass melting under the conditions of the operating facilities was studied. Field measurements of thermophysical properties were carried out, the recommendations on reducing the costs of the energy inputs of the snow melting process and the time of snow mass processing were developed. It was stated that the efficient operation of the retention facilities for industrial surface runoff treatment designed by «MosvodokanalN Iproject» JSC could be maintained throughout the year and served as an example of a water conservation solution.
